Fig 4. Genetic structure of the 44 Calotriton asper populations.
Genetic structure of the 44 Calotriton asper populations. A) Results of Bayesian clustering and individual assignment analysis obtained with STRUCTURE at K = 2 including all Calotriton asper populations (above), the western Pyrenean populations with K = 2 and the central-eastern Pyrenean populations with K = 3. Each individual is represented by a thin bar corresponding to the sum of assignment probabilities to the K cluster. Black bars separate populations. B) Map of the five genetic clusters.
